Ferrari launches upgraded FXX-K track-only supercar

Iconic Italian brand Ferrari today debuted a set of tweaks for its track-biased monster – the LaFerrari-based FXX-K supercar. Now named the FXX-K Evo, it's been given newly fettled aerodynamics and has a reduction in weight, making it arguably the most extreme Ferrari ever to roll out of the Marranello factory.

Ferrari's team has worked tirelessly to reduce weight on the already super-lightweight FXX-K. The company won't specify how much by, but it now comes in at under the 1,255kg of the previous car – that's less than many modern family hatchbacks. Mate that light weight with the 1,036bhp on tap from the electric motor and 6.3-litre V12 combo, and the FXX-K Evo is bound to be seriously fast – though Ferrari has not revealed any acceleration or top speed data.

The real magic comes from the FXX-K Evo's downforce. Ferrari has tweaked the aerodynamics of the vehicle to produce an incredible 640kg of downforce at 124mph – that's 23 per cent more than the previous FXX-K, and 75 per cent more than the vanilla LaFerrari.

Inside, the FXX-K Evo comes with a brand new steering wheel – it has built-in gearshift paddles along with controls for using the F1-inspired KERS (kinetic energy recovery system), a sophisticated party trick that gives the car a 'boost' when needed.

The company says it's the result of over 12,000 miles of development in total. Ferrari will be offering the FXX-K Evo as either an upgrade package for the very small number of existing FXX-Ks (only 40 were built) or as a standalone model, also built in excruciatingly low numbers.
